        "Tank transfer",
        "Mock batch B starts 100 U in vessel A. Verified event moves 80 U to vessel B2, leaving 20 U in A. Transfer is internal to the practice boundary."

    "answer": "BTL1 leaves 20 U in A and brings 80 into B2. BTL2 uses the executed 55 and documented five loss, yielding a calculated B2 closing of 20 U, not 15 from the plan. BTL3 observes 18, leaving a two-unit discrepancy without a supported cause. Preserve both calculated and observed closing figures and avoid adding the internal transfer as new inventory or inventing an extra loss.",
